My invention has reference to an improve" ment in the means for securing the lower edge portion of roll roofing, to the roofs of buildln s.

l ioll roofing has heretofore been secured to roofs, sidings and the like, by laying it lengthwise of the roof, the lower edge of an upper course overlapping the upper edge of the next lower course of roll roofing. is then secured to the roof or siding by driving nails through it into the roof orsiding. The nail holes thus formed in the roll roofing will cause it, sooner or later, to leak, thereby ruining the utility' of the roll roofing and the greater portion of all roll roofing leaks are caused by nail holes through the,

roofing material.

The object of my invention is to improve the means for securing roll roofing or the like to roofs, thereby eliminating the driving of nails or the like, through the overlap- V ping edge portion of the roll roofing.

A further object of my invention isto pro-..

vide roll roofing with roll roofing fasteners, each fastener being pivotally and permanently secured to the roll roofing and forming an integral part of the roll roofing.

Another object of my invention is to siInplify the'construction of roll roofing fasteners, whereby the cost of such duced to a minimum.

My invention consists in the peculiar and novel method and construction of means for fastening roll roofing to roofs and thevlike, said fastening means having details of 'construction, as will be more fully set forth hereinafter and claimed;

My improved roll roofing fasteners 8, 8, are constructed preferably of sheet metal in the form of an elongated narrow flat member having preferably rounded ends 10 and 11. In the rounded endportion 10 is a nail hole 12'and in the rounded end portion'll is a rivet slot 13. 7

Each fastening member 8 is movably and permanently secured to the roll roofing, adjacent its lower edge, by a rivet 14, which extends through the slot 13, in the fastening member 8. The inner head of is embedded in the roll roofing and is covered by the top coating.

The roll roofing 7, 7 is usually laid length- Wise of the roof, first a narrow strip at the roof edge and then the strips are laid full course overlapping the upper edge portion of 8, 8, in the position as shown in Figure 1, each fastenerjS is nailed in place by a nail 15, through the nail hole 12. This one nail 15, to each'fa'stener 8, is also driven through the upper edge portion of the next lower course i of roll roofing and into the roof boards 6, 6, thereby with one nail, securing the fastening the rivet 14 j 9 of the roll roofing, as

The next upper course of roll roofing 7 ,now being laid, is then given a downward semi-circular motion in the direction of the arrow 0, c,-Figur'es 1 and 2. When this next upper course of roll roofing has 60 The roll roofing 7, 7 has the usual top coating 9, 9, of asphalt or asphalt and ground in place,

reached its extreme downward movement, it has lapped over the upper edge portion of the next lower course of roll roofing, thereby giving the required lap to the roll roofing as shown in Figureafland 4. The rivet slot'lfi, in the fasteners 8,8, allows for expansion and contraction of the roll roofing, orfheroof boards.
